‘I truly required a break after that!’ Your most nerve-wracking TV episodes of all time

Spooks – I Spy Apocalypse (2003)

The episode begins with the intelligence unit locked down while undergoing a drill concerning a fictional terrorist event, overseen by two Home Office officials. As things progress, it appears that there really has been an attack and a chemical agent deployed. The suspense builds as messages indicate a disaster happening externally, and intensifies when the leader seems contaminated, and the government agents endeavor to depart, pushing the protagonist portrayed by Matthew Macfadyen to opt for either shooting them or letting them go and potentially infecting the secure MI5 headquarters. As this is Spooks, his decision is predictable.

Threads (1984)

Threads had minimal funding but one of the most frightening programmes I’ve ever seen due to its harsh realism and grim official statistics. Viewed it recently following the initial broadcast; I frequently went to the Sheffield pub shown in the series which underscored the actuality and the offhand factual official statements that were transmitted. Continuing to be utterly horrifying decades on.

Severance – The We We Are from 2022

The first season finale of Severance has to be right up there among intense episodes. I was throughout the episode quite literally on the edge of my seat, pushing alongside Dylan to hold the switches that allowed the Innies to remain active, while yelling at the Innies to disclose their facts. The final climactic moment – “she survives!” – felt like an explosion.

Industry – White Mischief (2024)

Episode five of the third series of Industry caused my heart to pound. I had to pause and get up and exit the space repeatedly due to the immense extent of the reckless self-harm I observed. Rishi Ramdani faces serious trouble in his job and domestic life – overwhelmed by debt to loan sharks owing to his uncontrollable gaming, engaging in dangerous ventures with a bet on sterling which may result in huge losses for his employer. Naturally, he embarks on a betting frenzy, consumes excessive substances and alcohol and wins, loses, wins, is severely assaulted. Every time you think things cannot decline more, it deteriorates. There’s hope of redemption at the end of the episode but he squanders the opportunity, resulting in dreadful effects in the season finale. Certainly required a rest afterward!

Peep Show – Holiday from 2007

Peep Show is not inherently a tense series. But the episode Holiday includes such amounts of embarrassment that it can cause you to stand the whole episode, riddled with anxiety. It all ramps up once Jeremy and Mark find themselves being compelled to falsify about the canine they by chance collide with and subsequent attempts to dispose of it. You then occupy the remainder of the episode questioning whether it truly can be worse than incineration, and it can be!

The 2001 The West Wing episode The Two Cathedrals

No other viewing has been as gripping compared to my initial viewing the concluding episode of The West Wing’s second season. The installment begins with the consequences of the passing (in a road incident) of the president’s private assistant and reaches a crescendo with a crisis in Haiti, and the fallout from the non-disclosure of the president’s MS diagnosis, along with affirmation of his plan to seek re-election. Superb programming. Unequaled.

Bodyguard – episode one (2018)

The start of the British program Bodyguard, with the hero aboard a train with his young son, is for me one of the most intense episodes ever. He spots a Muslim woman going into the loo and senses something is wrong. The bomb squad is alerted, enter the train, and try to persuade the woman to take off her suicide vest. Suspense rises to a nearly intolerable level, until, indeed, the vest is disarmed.

Buffy the Vampire Slayer – The Body from 2001

Buffy comes into her home to realize her mom has deceased due to natural factors, which is the most unusual type of death in this paranormal series. The installment lacks any soundtrack, a sullen tone, and we view the installment through the lens of Buffy’s dismay upon uncovering her mother.

The Sopranos – Made in America (2007)

The final scene of the final episode of the program was incredibly anxious. And if you viewed it when it first premiered, you – at the start – didn’t understand the cause. Tony’s foes, genuine and fictional, were all overcome. This seems similar to the first season’s finale, right? “Think about the small elements.” However, the vibe is oddly threatening. Nearly Twin Peaks-like fear. The clan sits in an eatery. Meadow parks. Tony sorrowfully notifies Carmela problems are brewing with an additional associate working with the government. Meadow secures a parking space. Odd persons arrive at the eatery. Gaze at Tony(?) Meadow parks. Tony plays a track on the music machine. Meadow parks her car. The bell sounds, an individual enters. It cannot be Meadow, she is still parking. Tony looks up. Keep going. It stops. My spirit fell about 20 minutes later.

The Walking Dead – The Last Day on Earth from 2016

I stayed up to watch this episode at 2am. It was extremely gripping after the buildup of bad guy Negan discovering the characters, mercilessly mocking his targets and then leaving the victim unknown (concluded with a suspenseful moment). The victim’s POV shot and the subdued noises – ugh! {We then had to wait for season seven|We then needed to await season
